'New lathe chuck jaw screws'

I've just seen this thread and it is probably a bit late for you now but G & M Tools (Ashington) have a box of jaw screws from which I found the exact one I needed to repair my Burnerd 4-jaw. It needed to be dressed and carefully fitted but the 'repair' is permanent. Best to visit with broken item and then match it up from the many in the box!

Hi, whats wrong with TIG welding a similar piece of metal in place, if you do one weld then let it cool down, (anyway TIG welds that small dont get that hot), then grind away the excess, or use another chuck or collet to machine down the offending bits. By the way as said before DONT!!! hit the key or but a length of steel in the chuck jaws and belt that too, not only do you damage the screws and the chuck jaws, you can also put the chuck out of alignment with the back plate, even bending the holding down screws.

If you have some spare time, drill three or four holes into the outside rim of the back plate and make a HEAVY duty C spanner, to remove stubborn chucks, if you drill the holes properly they make good indexing marks.

Whilst it is desirable to get on with the current model,it is possible to make a chuck screw if necessary using something like EN24. After all that's what a lathe is for and we do already make more complicated parts for our models. I made such a screw some years ago and it is still going strong. Colin

I have just bought a Bernerd chuck 6" 4 jaw with a screw damaged similar to the ones shown in the pics. posted in this thread, I have a friend who I think will be able to weld this for me, how do I remove the screw from the chuck.
